L'invention concerne un système (1) servant à munir d'un revêtement au moins une face d'un substrat (2) en forme de bande, le système présentant au moins un rouleau applicateur supérieur (3) agencé au-dessus du substrat (1), au moins un rouleau applicateur inférieur (4) agencé au-dessous du substrat (2), et au moins un dispositif de déplacement (5) relié au rouleau applicateur supérieur (3) et permettant de faire varier une position du rouleau applicateur supérieur (3) par rapport au rouleau applicateur inférieur (4). L'invention vise à améliorer le fonctionnement d'un tel système (1). À cet effet, le dispositif de déplacement (5) est configuré de telle manière qu'il permet de faire varier la position de rouleau applicateur supérieur (3) par rapport au rouleau applicateur inférieur (4) en direction horizontale et transversalement à l'axe médian longitudinal (8) du rouleau applicateur supérieur (3).
